СПОСОБ ЭЛЕКТРОИСКРОВОЙ ОБРАБОТКИ ПУАНСОНА И МАТРИЦЫ ВЫРУБНОГО ШТАМПАMETHOD OF ELECTRO-SPLIC TREATMENT OF PUNCHER AND MATRIX OF CUT-OFF STAMP

За влено 24 августа 1961 г. за 742521/25-8 в Комитет но де,1ам и: обретений и открытий при Совете Министров СССРFiled on August 24, 1961, for 742521 / 25-8 to the Committee of the Committee of the Council of Ministers of the USSR

Опубликовано в «Бюллетене изобретений Л 19 за 1962 г.Published in the Bulletin of Inventions No. 19, 1962.

Известные способы электроискровой обработки пуансона и матрицы вырубного штампа электродом-проволокой обеспечивают зазор между пуансоном и матрицей, определ емый диаметром проволоки-электродаНедостатком известных способов  вл етс  невозможность уменьшить зазор между пуансоном и матрицей до величины, меньшей, чем диаметр проволоки-электрода.Known methods of electrospark machining of a punch and die punch die with an electrode-wire provide a gap between the punch and the die defined by the diameter of the electrode wire. A disadvantage of the known methods is the inability to reduce the gap between the punch and the die to a value smaller than the diameter of the wire electrode.

Предлагаемый способ позвол ет регулировать величину зазора. С этой целью пуансон и матрицу изготовл ют совместно из двух параллельно расположенных заготовок, а электрод-проволоку наклон ют под некоторым углом к нормали, проход щей через плоскости заготовок, и прошивают матрицу пуансоном также электроискровы-м способом.The proposed method allows adjustment of the size of the gap. For this purpose, the punch and the matrix are made jointly from two parallelly arranged blanks, and the electrode-wire is tilted at a certain angle to the normal passing through the planes of the blanks, and the matrix is pierced by the punch also in an electric spark method.

На фиг. I изображена схема расположени  заготовок и электродапроволоки по предлагаемому способу; на фиг. 2 - пуансон и матрица после .прошивки.FIG. I shows the layout of the blanks and the electric wire according to the proposed method; in fig. 2 - punch and die after flashing.

Заготовки / и 2 матрицы и пуансона устанавливаютс  параллельно друг другу на некотором рассто нии Я. Затем режущим инструментом, которым служит электрод-проволока 3 с диаметром d, известными способами одновременно вырезаетс  по заданному контуру матрица 4 и пуансон 5с таким расчетом, чтобы зазор между ними был равен нулю. rfpH этом электрод-лроволока 3, двига сь по периметру вырезаемого контура, наклонена под некоторым углом а к нормали, проход щей через плоскости заготовок 7 и 2. Таким образом, получаютс  матрица и пуансон, режущие кромки которых имеют одинаковую конусность, а зазор ними равен нулю.The blanks / and 2 dies and punch are installed parallel to each other at a certain distance I. Then the cutting tool, which serves as an electrode-wire 3 with a diameter d, simultaneously cuts the die 4 and the punch 5c along a predetermined contour so that the gap between them was equal to zero. The rfpH of the lovolok 3 electrode, moving along the perimeter of the cut out contour, is inclined at a certain angle a to the normal passing through the planes of the workpieces 7 and 2. Thus, a matrix and a punch are obtained, the cutting edges of which have the same taper to zero.

Дл  того, чтобы получить необходимый рабочий зазор Л между матрицей 4 и пуансоном 5, полученную матрицу прошивают -пуансоном электроискровым способом на режимах, обеспечивающих требуемую величин зазооа /i между ними. При этом матрица 4 и пуансон 5 служат электродами-инструментами друг по отношению к другу. При прошивке конусность матрицы и пуансона срабатываетс  при образовании зазорэ (на фиг. 2 сработанные конусности изображены пунктиром)In order to obtain the necessary working gap L between the matrix 4 and the punch 5, the resulting matrix is stitched with a punch in the electric-spark method on the modes that provide the required values of the gap between them. In this case, the matrix 4 and the punch 5 serve as instrument electrodes with respect to each other. When flashing, the taper of the die and punch is triggered when a gap is formed (in Fig. 2, the worked taper is shown in dotted lines)
